Same in Jitsi Meet. One workaround I found for the video choppiness (at the expense of image quality) is to present the video file as a virtual webcam using OBS Studio.

Not sure if this is the case on all platforms, but didn't OBS just add virtual camera in the most recent version (instead of via plugin)?

I noticed it the other day after an update, but not sure if it's only on the Windows version.

Maybe, if they did that's great!
